ABSTRACT:
A composition and process are provided for making precipitated biconstituent cellulose-polyvinyl alcohol shaped articles by dissolving polyvinyl alcohol and cellulose in a tertiary amine oxide solvent containing from about 0.8 to about 29% water to form a biconstituent dispersion wherein the cellulose and polyvinyl alcohol comprise distinct phases, preferably with the two solutions codispersed within each other. Shaped articles can be formed from the biconstituent dispersions of the invention.
